• When a condition becomes true 

• When a condition becomes false 

• After a fixed number of iterations

What is the purpose of the continue statement in a loop?

• To exit the loop immediately 

• To skip the rest of the current loop iteration and proceed to the next iteration 

• To restart the loop from the beginning
